on Friday, March 17th 2017, from 5:00 to 6:00 (UTC) this blog as well as MAXON Labs (plus a few other MAXON services) will be down for maintenance. For developers this mainly means, that neither SDK docs (C++, Python, Melange) nor the user help will be available online.
So, if you do not belong to the people sleeping during that time, but instead plan to do plugin development, then you may want to visit the download page now, in order to get what you need.
Sorry for any inconvenience caused by this downtime.
your SDK Team
